Re: 01A noise

Yep, ruled out, unfortunately. There's quite a bit of backlash in the
front diff, almost none in the rear. Rear diff mounts and propshaft check
OK. When hot, the front diff makes a clik-clik noise when rotated. And,
when I drained the tranny oil, it was brown and metallic looking, and up
through the drain hole, I could see a ring and pinion that looked sharp
enough to shave with. Don't get me wrong, I wish you were right...
